The biggest oil producer in the United Arab Emirates plans to develop a carbon capture project that will nearly triple its capacity to remove the gas from the atmosphere to store it below ground.

Abu Dhabi National Oil Co. has taken the final investment decision to develop a project that will capture 1.5 million tons a year of carbon dioxide emissions from its Habshan natural gas processing facility, the company said in a statement. It didn’t provide a cost estimate for the project.

The carbon dioxide gas that’s captured will be pumped into an oil field where it will be used to boost output in a process known as enhanced oil recovery, Musabbeh Al Kaabi, Adnoc’s head of low carbon solutions and international growth, said in an interview. The carbon will be permanently stored in the underground caverns and contribute to Adnoc’s target to have net zero emissions by 2045, he said.

Adnoc, the government producer based in the UAE capital, already operates a facility that captures 800,000 tons per year of carbon from a steel plant in the emirate. The new project, which is set to be in operation by 2026, will boost the emirate’s carbon capture capacity to 2.3 million tons per year.
